Description

Technical Field

[0001] The utility model relates to the technical field of yellow phosphorus tail gas recycling, in particular to a yellow phosphorus tail gas combustion device. Background Technique

[0002] The boiler for burning and utilizing yellow phosphorus tail gas is a device specially designed to recover and recycle the heat energy in industrial waste gas. The core function of this boiler is to convert the combustible components in the yellow phosphorus tail gas into heat energy, and then heat the boiler medium to achieve efficient energy utilization. After a large number of searches, the publication number is CN220567260U, which discloses a yellow phosphorus tail gas combustion device. Cooling water is injected into the combustion furnace and the middle layer through a circulating water pump to promote the temperature reduction in the spiral furnace chamber. However, both the spiral furnace chamber and the interlayer are made of materials with excellent temperature resistance and heat insulation effects. Therefore, the heat dissipation of the cooling water will only keep the furnace chamber temperature at a balanced level that forms a negative feedback on the flame temperature, prompting the flame to radiate more heat outward, so that the flame temperature is maintained at a stable high temperature state.

[0003] However, in the existing technology, when the device is in use, some impurities may be generated during the combustion of yellow phosphorus tail gas. These impurities may adhere to the furnace wall. The sediment on the furnace wall will form a heat insulation layer, reducing the effective conduction of heat energy by the furnace wall and lowering the heat exchange efficiency between the inside of the furnace and the heating boiler medium, thereby causing the performance of the waste heat recovery system to also decrease. For this reason, a yellow phosphorus tail gas combustion device needs to be proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a yellow phosphorus tail gas combustion device, which has the advantages of cleaning the sediment on the furnace wall, thereby reducing the influence of impurities on the heat conversion efficiency and waste heat recovery and reuse on the furnace wall, and solves the problem that impurities are formed during the combustion of yellow phosphorus tail gas and adhere to the furnace wall, thereby causing the performance of the waste heat recovery system to also decrease.

The innovative design of the driven wheel allows its front end to rotate and install the fixing frame. At the same time, the front end of the driven wheel passes through the center of the fixing frame and is fixedly connected to the rear end of the scraping frame. This design not only ensures the stability of transmission but also improves the efficiency of power transmission, guaranteeing the smooth operation of the scraping frame.

[0009] Preferably, a support frame is fixedly installed at the bottom of the furnace body. The bottom of the support frame is fixedly connected to the upper surface of the base. In the design, the support frame at the bottom of the furnace body provides additional stability.

[0010] Preferably, the rear end of the outer shell is designed with an open structure. The rear end of the outer shell is fixedly connected to the front surface of the fixing frame. An exhaust smoke groove is opened and communicated at the front end of the lower front surface of the outer shell. In the design, the rear end of the outer shell is designed with an open structure, the fixed connection between the rear end of the outer shell and the front surface of the fixing frame, and the exhaust smoke groove opened and installed at the front end of the lower front surface of the outer shell together constitute an efficient exhaust smoke path.

[0011] Preferably, the water inlet pipe and the water outlet pipe are communicated and installed through the partition frame on the opposite side of the cylinder body and the outer shell.
